To all whom t may concern.

Be it known that we, CHARLEs L. BASTIAN and HJALMAR MA'rHisnN, citizensot the United States, residing at Chicago, in the county of Cook andState ot Illinois, have invented certain new and useful improvements inDispensing Valves, of which the following is a specification.

'lhis invention relates to dispensing devices for carbonated beveragesand has particular reference to the, dispensing valve. rlhe primaryobject of the invention is to produce a simple valve which will supplyplain water in a coarse stream, and carbonated water in either a coarseor ne stream.

Another object of the .invention is to produce a valve structure inwhich a single movable valve member will control the flow ot the twoliquids and supply one of them in either a coarse or a tine stream, asdesired.

@ther objects will become apparent as the description is read inconnection with the accompanying drawing showing a selected embodimentof the invention, and in whichlig. 1 is a plan view showing thedifferent .positions of the valve handle in dotted lines;

Fig. 2 a vertical section view;

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2,sliowinv the arrange ment ot outlet ports in the valve casing; and

Fig. 4 is a transverse section on the line 1 -4i of Fig. 2 showing thearrangement oic ports in the valve.

Referring to the'reiierence numerals on the drawing, indicates the valvecasing having a chamber 11 therein and being litted at its upper endwith a bonnet 12 screwthreaded thereto as indicated at 13. @ne side otthe casing is provided with a threaded nipple 14 adapted to receivecoupling 15 by which the valve is secured to draft arm 16. lNithin thedraft arm are arranged a pipe 17 for plain water, and a pipe 13 forcarbonated water. The pipe 17 is connected with the chamber 11 by apassage 19., and the pipe 18 is connected with the chamber 11 by anangular passage 2O which enters the chamber at the center oit itsbottom. The bottom of the chamber is supplied with an outlet passage 21for plain water and outlet passages 22 md 23 tor carbonated water. 'lhepassage 22 is connected wit- DSPENSTNG VALVE.

a jet nozlzle 24 while the passages 21 and 23 communicate with thenipple 25 having a spray grating 26 and equipped at its lower end witha. hard rubber nozzle 27. The ob- ]ect of the grating 26. is to break upthe stream ot either p ain or carbonated water and make it tall from.the nozzle 27 in a solid stream inthe customary manner.

A valve gasket or packing 28 of leather or other suitable material ispressed tightly into the chamber, against the botton o1 the chamber, andhas passages forming continuations of the passages 21, 22 and 23. Seatedon this gasketor packing is a rotary valve 29 having a stem 30 journaledin the bonnet 12 and equipped with a stuling box 31 and an operatinghandle 32. rlhe valve has a large passage 33 extending therethrough andadapted to align with the passage 21 to establish communication betweenthe pipe 17 and the spray nozzle 27, and another passage 34 somewhat{Ll-shaped in form, to establish communication between the passage 20and the assages 22 and 23. @nel arm 35 of this [tl-shaped passage isco-axial with the disc and aligned with the passage 20, and the otherarm 36 or this passage is substantially parallel to the arm 35 andcoinmunicates through the same side of the valve with the passages 22and 23.

Nonmally, the position of the handle 32 shown in Fig. 1 corresponds tothe position ot the valve when all outlet passages are closed. By movingthe handle to the dotted line position A, the passage 33 inthe valve isaligned with the passage 21 in the valve casing, and plain water isallowed to pass freely from the pipe 17 through the passage 19 into thechamber 11, and thence through the valve and in the bottom ot the casingto the spray nozzle 27. By moving the handle to the dotted line positionl5, in Fig. 1., the arm 36 oit the passage 34C is aligned with thepassage 22 in the bottom of the casing, and carbonated water can passfreely from the pipe 13 through the passage 20 to the passage 3a and thepassa-ge 22, to the spray nozzle 211. By placing the handle in thedotted .line position C, the arm` 36 oi' the passage 3a is aligned withthe'passage 23 in the valve casing, and carbonated water is sup e pli edto the spray nozzle 27.

.ln order to hold the valve 29 properly seated on the gasket 23, weprovide a spring 37 wound about the stem 30 and pressed between thebonnet andthe valve disc; to eli` ininate friction as much as possible,the ball bearings-38 are interposed between the bonnet and a ball race39 on to of the spring.

From the foregoing it willl be obvious that we have produced a verysimple construction whereby plain water may be supplied l1 n a coarsestream, and carbonated water in' either a coarse or a fine straem. Thisconstruction, moreover, practically eliminates all leakage common to thespring and check valves heretofore used. B putting all the ports underthe control o a single rotary valve, we produce a very simple devicewhich practically never gets out of order, or requires adjustment.

We are aware that changes in the form and proportion and arrangement ofthe parts of our invention may be made without departin from the spiritor sacrificing any of the a vantaves thereof, and we therefore reservethe rig'lfxtto make all such changes as fairly fall within the scope ofthe following claims.
